DOPAMINE (PLASMA)

The DOPAMINE (PLASMA) test measures the concentration of dopamine circulating in blood plasma. Collected via a venous blood draw and analysed using laboratory methods such as HPLC or mass spectrometry, it quantifies peripheral dopamine to help evaluate disorders of catecholamine production and to monitor the systemic effects of medications that alter dopamine levels.

This at‑home service in Dubai is performed by certified UAE phlebotomists, offering convenient sample collection for patients who require regular monitoring or who prefer home care. Plasma dopamine measurement is useful in assessing suspected catecholamine‑secreting conditions, evaluating autonomic dysfunction, and reviewing medication effects, but results must be interpreted by a clinician because levels are sensitive to posture, stress, diet and concurrent drugs.
